The diagram below shows that one strand of the DNA double-helix serves as a template for the construction of mRNA. The sequence of nucleotides in this DNA strand is complimentary (opposite) the sequence in mRNA. The diagram also shows that the sequence of nucleotides in mRNA determines the amino acids in the protein.

Legend: Illustration of the double helical structure of the DNA molecule. ... Each spiral strand, composed of a sugar phosphate backbone and attached bases, is connected to a complementary strand by hydrogen bonding (non- covalent) between paired bases, adenine (A) with thymine (T) and guanine (G) with cytosine (C).

The emergence of the grooves has to do with modeling each nucleotide as a rigid 'L'. When the angle of the backbone--the part of the nucleotide that is not the base--relative to the direction of the DNA strand is increased, the base must tilt downwards to accommodate the change.

The diagram below shows a working model of how DNA double strand break induced recombination can occur. ... In this model gene conversion can be described as the transfer of genetic information from one DNA strand to a recipient sequence. For example, if the invading strand contains a mutation, then that mutation can...

This same phosphate ion uses another oxygen to bond to the third carbon in another sugar molecule, and this repeated chain forms the backbone of a DNA strand. (See diagram #1 below.) But since DNA is double stranded, there are two sugar phosphate backbones.
